By Jussi Hermansen, In a groundbreaking collaboration, EMerald, SkyTEM, SDU, and NGI have joined forces to propel the future of geomodelling through the innovative AGAVE Project. This visionary initiative, acronymized as “AI-based Geo-models from UAV Geoscanning for sustainable infrastructure development” (AGAVE), marks a significant leap forward in the realm of geospatial exploration and sustainable infrastructure planning. For the first time in Europe, this pioneering project achieved a historic milestone by securing permission for a sizable drone, equipped with an external load, to operate beyond controlled airspace. The synergy between EMerald’s technological prowess, SkyTEM’s expertise in airborne geophysics, SDU’s academic excellence, and NGI’s leadership in geotechnical research has yielded unprecedented results.AGAVE’s objectives included the reduction of equipment size and weight, enabling the application of measuring instruments by UAVs or drones. Through the integration of a high-resolution ground investigation workflow, featuring a geoscanning system carried by a UAV, machine-learning-based data integration, and a significantly scaled-back invasive sampling program, the project seeks to elevate sustainability in the construction sector. Harnessing drone-based technology will enable flights at lower altitudes, thereby enhancing measurement accuracy and resolution in the initial meters of the subsurface.AGAVE’s objectives included the reduction of equipment size and weight, enabling the application of measuring instruments by UAVs or drones.

Pfaffhuber, CEO, EMerald GeomodellingThroughout the AGAVE project, two pivotal achievements have significantly advanced the development of the drone-based system. Firstly, obtaining approval for flying the drone system is a noteworthy milestone, representing, to the best of our knowledge, the first instance of its kind in Europe. This accomplishment, led by project partners SkyTEM and SDU, was corroborated during field tests in Denmark. The data acquired from the drone demonstrated superior resolution compared to data collected from the same location using ground-based geophysical methods. System tests conducted in Norway and Denmark displayed the capacity to present real-world data with the current version of the instrument. This outcome, validated and deemed a notable achievement within the project, was particularly highlighted during geotechnical assessments carried out by project partner NGI in Norway. Notably, a representative smaller system was tested using a helicopter, displaying the versatility and applicability of the new generation results.Achieving successful approval for the Specific Operations Risk Assessment (SORA) of such an intricate and heavy-duty platform and payload feels like a dream coming true. Just a few years ago it would have been considered impossible to get permission to operate such a system.Jussi Hermansen, Senior specialist, SDUThe road aheadThe system has already received approval in Denmark, and the next phase after AGAVE involves transferring the approval to Norway over the next year, in collaboration with project developers and contractors. Once fully developed, EMerald aspires to elevate the system to become the new standard for geotechnical investigations, thereby reducing service costs and increasing the sustainability of infrastructure investments.Drone-based survey systems are a turning point in our industry and remind us of the paradigm shift caused by the introduction of helicopter-based TEM, which disrupted the fixed-wing TEM market. It makes surveys more financially accessible for smaller-scale projects and demonstrates our dedication to our mission of promoting sustainable surveying.Kristoffer Skovgaard Mohr, Head of R&D and Manufacturing, SkyTEM SurveysThe solution will also open doors to new markets in the future. The current helicopter-based solution carries a substantial entry cost while offering comparatively lower resolution, limiting the return on investment for smaller infrastructure projects reliant on precision and constrained ground investigation budgets. The UAV-based workflow, on the other hand, emerges as a viable solution, promising lower costs, faster deployment and superior accuracy and resolution. The AGAVE project symbolizes a milestone for all the partners involved and has set the stage for exciting developments in the future. The key element of the combined value chain starting with SkyTEM’s high-definition geophysical data and ending with EMerald’s ML–crafted 3D models is to provide subsurface information simply and rapidly. Scaling this value proposition in the coming years powered by a transition from helicopters to UAVs has the potential to disrupt.Andi A. Pfaffhuber, CEO, EMerald GeomodellingPart of the Eurostar ProgramThe Eurostar program, a joint program between EUREKA and the European Commission, is designed to support innovative projects led by research and development performing small and medium-sized enterprises. Supported by funding from the European Union through Horizon 2020, this program empowers small enterprises to accomplish remarkable things.The pioneering AGAVE project initiative and the partnership of Emerald Geomodelling, SkyTEM, SDU and NGI was supported by Eurostar funding, acknowledging the need for wider spread geological understanding of the earth beneath our feet, supporting more sustainable solutions.AGAVE project team key representatives including from left to right: Flemming Effersø, Guro Skurdal, Kristoffer Mohr, Jussi Hermansen, Craig Christensen, Magnus Rømoen, Nicklas Nyboe, Martin Panzner & Andi Pfaffhuber.
